A method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure. A femoral implant achieves intramedullary fixation as well as fixation into the femoral head. To optimally position the femoral implant, a minimally invasive incision is aligned with the greater trochanter and the wound is developed to expose the greater trochanter. Various reamers are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur.

What is claimed is: 1. An orthopedic implant for implantation into a cavity formed within an anatomical structure, comprising: a bag including a fill access providing access to an interior of said bag; a structural support disposed at least partially within said bag, said structural support defining an outer periphery transverse to a longitudinal axis of said structural support; and a lag cooperating with said structural support, said lag including a head, said head including a thread extending radially outwardly from said lag, said thread having an outer diameter extending beyond said outer periphery of said structural support, said structural support comprising a tube having an exterior wall and an interior wall defining a hollow interior; and a retaining ring circumferentially capturing said bag against said tube. 2. The orthopedic implant of claim 1, wherein said bag is fixedly secured to at least one end of said tube. 3. The orthopedic implant of claim 1, wherein said tube includes insertion tool engagement structure. 4. The orthopedic implant of claim 1, further comprising a lag, said lag cooperating with said structural support. 5. The orthopedic implant of claim 1, wherein said bag comprises at least one material selected from the group consisting of biocompatible acrylic material, polymer material, glass fiber material, ceramic fiber material, stainless steel fiber material, titanium fiber material, titanium alloy fiber material, tantalum fiber material, shape-memory material, and hydrogel materials. 6. An orthopedic implant for implantation into a cavity formed within an anatomical structure, comprising: a bag including a fill access providing access to an interior of said bag; a structural support disposed at least partially within said bag, said structural support comprising a tube having an exterior wall and an interior wall defining a hollow interior; a retaining ring circumferentially capturing said bag against said tube; and a lag, said lag cooperating with said structural support; wherein said lag comprises at least one radially expandable finger. 7. The orthopedic implant of claim 6, wherein said lag comprises a plurality of radially expandable fingers. 8. The orthopedic implant of claim 7, wherein said lag has a central axis and upon axial compression of said lag along said central axis, said radially expandable fingers are deformable to radially expand. 9. An orthopedic implant assembly for implanting an orthopedic implant into a cavity formed within an anatomical structure, comprising: an orthopedic implant, said orthopedic implant comprising: a bag including a fill access providing access to an interior of said bag; a structural support disposed at least partially within said bag, said structural support including first engagement structure, said structural support comprising a tube having an exterior wall and an interior wall defining a hollow interior; a retaining ring circumferentially capturing said bag against said tube; and a lag, said lag cooperating with said structural support; an implant insertion tool including second engagement structure engageable with said first engagement structure, said implant insertion tool including at least one passage which is placed in fluid communication with said fill access of said bag upon engagement of said first engagement structure with said second engagement structure. 10. The orthopedic implant assembly of claim 9, wherein said bag is fixedly secured to at least one end of said tube. 11. The orthopedic implant assembly of claim 9, wherein said first engagement structure comprises one of a projection and a recess, and said second engagement structure comprises the other of a projection and a recess. 12. The orthopedic implant assembly of claim 9, wherein said bag comprises at least one material selected from the group consisting of biocompatible acrylic material, polymer material, glass fiber material, ceramic fiber material, stainless steel fiber material, titanium fiber material, titanium alloy fiber material, tantalum fiber material, shape-memory material, and hydrogel materials. 13. An orthopedic implant assembly for implanting an orthopedic implant into a cavity formed within an anatomical structure, comprising: an orthopedic implant, said orthopedic implant comprising: a bag including a fill access providing access to an interior of said bag; a structural support disposed at least partially within said bag, said structural support including first engagement structure; and a lag, said lag cooperating with said structural support, said lag comprising at least one radially expandable finger; an implant insertion tool including second engagement structure engageable with said first engagement structure, said implant insertion tool including at least one passage which is placed in fluid communication with said fill access of said bag upon engagement of said first engagement structure with said second engagement structure. 14. An orthopedic implant assembly for implanting an orthopedic implant into a cavity formed within an anatomical structure, comprising: an orthopedic implant, said orthopedic implant comprising: a bag including a fill access providing access to an interior of said bag; a structural support disposed at least partially within said bag, said structural support including first engagement structure; and a lag, said lag cooperating with said structural support, said lag comprising a plurality of radially expandable fingers; an implant insertion tool including second engagement structure engageable with said first engagement structure, said implant insertion tool including at least one passage which is placed in fluid communication with said fill access of said bag upon engagement of said first engagement structure with said second engagement structure. 15. An orthopedic implant assembly for implanting an orthopedic implant into a cavity formed within an anatomical structure, comprising: an orthopedic implant, said orthopedic implant comprising: a bag including a fill access providing access to an interior of said bag; a structural support disposed at least partially within said bag, said structural support including first engagement structure; and a lag, said lag cooperating with said structural support, said lag has a central axis and upon axial compression of said lag along said central axis, said radially expandable fingers are deformable to radially expand; an implant insertion tool including second engagement structure engageable with said first engagement structure, said implant insertion tool including at least one passage which is placed in fluid communication with said fill access of said bag upon engagement of said first engagement structure with said second engagement structure.
